| Impact Description | By changing the composition of the lower food web, P. phoxinus has the potential to alter predator-prey relationships. Following the introduction of Phoxinus phoxinus, the composition of the littoral benthos changed from one that was once dominated by Ephemeroptera, Trichoptera, Plecoptera, and Gammarus lacustris to one that is dominated by chironomids and oligochaetes. |
